A disposable tourniquet is a vital tool used in hospitals, clinics, and laboratories to temporarily restrict blood flow in a limb during procedures such as drawing blood or inserting an IV. It helps veins become more visible and easier to access.
At RONGHAI Medical Technology Co., Ltd., we manufacture high-quality Kimao disposable tourniquets made from medical-grade materials, ensuring safety, comfort, and excellent elasticity.
This guide explains how to correctly apply a disposable tourniquet, when to use it, and key precautions for safe medical practice.

1. Understanding What a Disposable Tourniquet Is

A disposable tourniquet is a single-use elastic band designed to temporarily stop venous blood flow while allowing arterial circulation. It creates mild pressure to make veins more visible and easier for medical personnel to access.

Features of RONGHAI Disposable Tourniquets

• Made from natural rubber or high-grade silicone with soft elasticity

• Latex-free options available to prevent allergic reactions

• Non-slip surface to ensure secure placement

• Adjustable length for adults, children, and different limb sizes

• Individually packaged for hygiene and infection control

RONGHAI’s disposable tourniquets are widely used in hospitals, clinics, and blood collection centers worldwide due to their ease of use, hygiene, and patient comfort.

2. Preparation Before Applying the Tourniquet

Before applying the tourniquet, it’s important to ensure the right environment, equipment, and procedure steps to protect both patient and practitioner.

1. Gather Necessary Materials

• Disposable tourniquet (RONGHAI brand)

• Alcohol swabs

• Gloves

• Sterile gauze or cotton

• Blood collection kit or IV setup

2. Check the Patient and Site

• Explain the procedure to the patient to reduce anxiety.

• Inspect the limb for wounds, inflammation, or fragile veins — never apply a tourniquet over injured or swollen areas.

• Choose the appropriate site, usually the upper arm for venipuncture.

3. Wash and Sanitize

• Wash your hands thoroughly with soap or sanitizer.

• Put on sterile gloves to prevent contamination.

• Ensure the disposable tourniquet is clean and intact — do not use if damaged or contaminated.

3. Step-by-Step: How to Apply a Disposable Tourniquet

The process should be quick, gentle, and precise. Follow these steps for correct application.

Step 1: Position the Tourniquet

• Place the tourniquet around the upper arm, approximately 7–10 cm (3–4 inches) above the intended puncture site.

• Smooth out any wrinkles to prevent pinching or uneven pressure.

Step 2: Tighten the Tourniquet

• Hold both ends of the tourniquet and pull gently to create tension.

• Cross one end over the other, forming a simple loop or half-knot, or secure it with a fast-release buckle if available.

• Ensure it is tight enough to make veins visible, but not so tight that the patient feels pain or numbness.

RONGHAI Safety Tip: The patient should still feel a pulse below the tourniquet. Excessive pressure can block arterial blood flow and cause discomfort.

Step 3: Locate the Vein

• Ask the patient to make a fist without excessive squeezing.

• Observe the forearm veins — the median cubital vein is typically the most suitable for venipuncture.

• Gently palpate the vein to confirm its position.

Step 4: Perform Venipuncture or IV Insertion

• Clean the puncture site with alcohol and allow it to dry.

• Insert the needle into the vein according to standard medical protocol.

• Once the needle is properly placed and blood flow is established, proceed to release the tourniquet.

Step 5: Release the Tourniquet

• Loosen or unfasten the tourniquet immediately after blood flow begins or within 1 minute of application.

• Allow blood circulation to return to normal before continuing the procedure.

Important: Prolonged application can cause vein collapse, pain, or hemoconcentration. Never leave the tourniquet in place for more than one minute.

Step 6: Dispose of the Tourniquet

• Remove and discard the tourniquet after single use.

• Place it in a medical waste container to prevent cross-contamination.

• Sanitize hands and prepare for the next step of patient care.
